Crash when last line is smaller than truncate label.
NSRange tokenRange = [truncationString.string rangeOfString:attributedTruncationString.string];
NSRange tokenLinkRange = NSMakeRange((NSUInteger)(lastLineRange.location+lastLineRange.length)-tokenRange.length, (NSUInteger)tokenRange.length);
(lastLineRange.location+lastLineRange.length) < tokenRange.length
Then casting to NSUInteger, it return a very big number.
I think I may be seeing a similar crash. I am setting a attributedTruncationToken and just setting a normal string. This is the stack

Also worth noting that if I don't set NSLinkAttributeName as an attribute of the truncation token the crash does not happen. But if I don't do that how can I use the truncation token as a link..?
Any updates for this?
I've experienced a similar issue recently and it's an issue when the line has a length less than the truncation tokens length.
@joshuafeldman Removing NSLinkAttributeName stops the crash but kills the link functionality.
I've created a write up and included the demo project here on my Github
On a side note, Is this project still maintained?
Hello guys,
How can I fix this? Thanks you
